Black Caviar's daughter Oscietra has made an immediate impression in her first public appearance, winning a jump-out at Flemington as she builds towards a highly anticipated race debut.

The two-year-old filly, the first foal out of the champion mare who was undefeated in her 25 starts, flew out of the barriers in Friday's 800m hit-out to lead her trial and was never headed as she won the five-horse heat by about a length.
